[PATCH] [media] drivers/media/pci: Variable vbi.type could be uninitialized if macro v4l2_subdev_call set __result an error code

[Yizhuo]

Inside function compress_sliced_buf(), variable vbi.type is
uninitialized if macro v4l2_subdev_call set __result an
error code. However, vbi.type is used in the if statement
without any check, which is potentially unsafe.
